CP Piston BRS BBC 4.610 Bore 4.375 Stroke 6.535 Rod Set Of 8 (MTO Non-Cancel)

This is a set of eight forged pistons from CP Pistons, specifically made for big block Chevrolet (BBC) engines. These pistons are designed for a 4.610 inch bore, a 4.375 inch stroke, and use a 6.535 inch connecting rod. Because these are made to order, they cannot be canceled once the order is placed, so be sure this is exactly what you need for your build.

CP Pistons are well-known in the performance engine building world for their robust construction and attention to detail. These particular pistons are forged from high-strength aluminum alloy, which offers a great balance of durability and weight savings. The forging process creates a grain structure that is much stronger than cast aluminum, making these pistons capable of handling the extreme pressures and temperatures found in high-performance applications. The specific dimensions – 4.610" bore, 4.375" stroke, and 6.535" rod length – are critical for achieving the correct compression ratio and piston-to-wall clearance for your specific engine combination. Proper clearance is essential for preventing piston slap and ensuring longevity under heavy load.

When building a high-performance engine, the pistons are a foundational component. These CP Pistons are a solid option for builders looking for reliable, strong internals. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation guidelines to ensure proper fitment and assembly.
